GeForce GTX 555

2011

Why buy it

✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Trade-offs

❌Lower average FPS than Radeon 630 across 50 tracked games in our benchmark data.
❌Very weak future-proofing: 2011-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌
50% HIGHER MSRP
$150 MSRPvs$100 MSRP
❌Lower G3D Mark per dollar, at 10.7 vs 15.8 G3D/$ ($150 MSRP vs $100 MSRP).
❌40% higher power demand at 70W vs 50W.

Radeon 630

2019

Why buy it

✅31.7% more average FPS across 50 tracked games in our benchmark data.
✅Costs $50 less on MSRP ($100 MSRP vs $150 MSRP).
✅Delivers 47.3% more G3D Mark for each dollar spent, at 15.8 vs 10.7 G3D/$ ($100 MSRP vs $150 MSRP).
✅Less risky long-term buy than GeForce GTX 555: it remains the more sensible modern option while GeForce GTX 555 is already obsolete for modern gaming.
✅Draws 50W instead of 70W, a 20W reduction.

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌Poor future-proofing: 2019-era hardware with 512 MB of VRAM is already a legacy-tier option for modern games.

Quick Answers

So, is Radeon 630 better than GeForce GTX 555?

Yes. Radeon 630 is the better GPU overall here. You are getting 31.7% more average FPS across 50 tracked games in our benchmark data and 1.8% higher PassMark G3D performance. It also comes from 2019 instead of 2011, which helps its case as the more complete modern gaming card.

Which one is more future-proof for 2026 and beyond?

Radeon 630 is the more future-proof choice for 2026 and beyond. You are getting a newer 2019 generation instead of 2011, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, and a 14nm process instead of 40nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

Which one is the smarter buy today, not just the cheaper card?

Radeon 630 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon 630 is about $50 cheaper on MSRP at $100 MSRP versus $150 MSRP, and you are getting 31.7% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (1,575 vs 1,604). It also leads G3D-per-dollar by 47.3%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is GeForce GTX 555 still worth buying for gaming in 2026?

Yes. GeForce GTX 555 is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around $150 MSRP, even if Radeon 630 is still the cleaner recommendation on overall value today.
